Aimiya Zero (相宮零) is an utaite who hasn't confirmed their gender yet. In some initial covers, Aimiya Zero mostly sang in low ranges, such as in the cover of "orange" or "Karakuri Pierrot -Acoustic ver.-". In contrary, most covers were sung with a cute, soft and high voice. Aimiya Zero can be considered as a ryouseirui.

"Asu no Yozora Shoukaihan" is the most popular cover of Aimiya Zero, with approximate 85k views as of December 2015.

Although being called "Aimiya" by the fellows, Aimiya Zero only names the covers with "零" (Zero) and sometimes, it makes people confused with the other utaite Zero. Shimizu Tatsuya is Aimiya Zero's closest friend. They collaborated in many duet covers, even had a liveshow "Anmitsuya" together on October 24, 2015.
